.SH NAME
acct \- enable or disable process accounting
.SH SYNOPSIS
.LP
.nf
#include <unistd.h>

\fBint\fR \fBacct\fR(\fBconst char *\fR\fIpath\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBacct()\fR function enables or disables the system process accounting
routine. If the routine is enabled, an accounting record will be written in an
accounting file for each process that terminates. The termination of a process
can be caused by either an \fBexit\fR(2) call or a \fBsignal\fR(3C)). The
effective user \fBID\fR of the process calling \fBacct()\fR must have the
appropriate privileges.
.sp
.LP
The \fIpath\fR argument points to the pathname of the accounting file, whose
file format is described on the \fBacct.h\fR(3HEAD) manual page.
.sp
.LP
The accounting routine is enabled if \fIpath\fR is non-zero and no errors occur
during the function. It is disabled if \fIpath\fR is  \fB(char *)NULL\fR  and
no errors occur during the function.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fB0\fR is returned. Otherwise, \fB\(mi1\fR is
returned and \fBerrno\fR is set to indicate the error.
